In the conversion or adaptation of vehicles such as motor driven trucks fonspeoi'el uses, as for the ropulsion of snow plow equip ment and the like; it is usually necessary to provide an extension for the frame by which. connection to the equipment can be made.

snow plow equipment this presents a 0011- slde'rable problem as the trucks for example,

spring nd must be relee'sed'iorothen ork with as little deleiy' as possible.

Whil thees embly must be done rapidly;

. it must be done accurately es-fo'r example where a snow low hose' is" to be mou ted on a truck. For such werhimme extensions or push beams must be rigid and make con? motion with the plow nose at predet rmined points. Such a plow nose'nnist heve'pfopei degrees of clearance fromtheroad and trucks vary considerably in'the height of frame it is necessary that the pu h beetlfis be made to compensate forsuch difl-erences;

Our i vention therefore contemplates a! system f clamping or mounting push beanie, or the like on the'fi'z'tmes of trucks or" other motive equipment so asfno'tonly to oofn pensate for differences in; height, but also.

differences in the size of frames both" as to depth and Width.

These and variou other features which will be later discussed are shown in illii's=; tretive mbodiment pgesent in the ac'oln enying drawing The n w plow equip m nt is selected for illustration because it is characteristic and because it represents at field of" important development made HeG'esf- SaIfy by modern systems ofo'ornmnnioetion.

bolt heads are let into channels 9 formed on one of the inner faces of the main member 6 so that the bolts 8 are held against rotation when the nuts 10are tightened up. The mem- 5 ber 6 is provided on its outer face with an ex- .ternal portion 6 corrugated as at 6 to provide a serrated way and said member 6 is I adapted to cooperate with a beam or arm bolted securely thereto. bybolts 1 3 theheads V 14 of which are held against rotation inslid able cradles 15 which are guided during ads justment in a slot 16 in the member 6. In this way the push arm or pushbeam clamp mem:

bers '11 and12 are adjustable vertically so as to position the end] of the push arm or beam 5 either up orvdownto secure the desired tilt necessary to bring the push rod f in the proper'p ositirm relative to the plow nose 2. Thememberll is providedwith flange-re ceiving bosses 11 and the member, 12with oppositely faced corresponding bosses 12 T hese,as shown in Fig.8 are rounded on their flange receiving facesso as to permit the tilt I 5;. of the push'arm or beam 5' relative to the frame member 1 of the truck. ,Inthis way the push arm orbe am 5 maybe firmly clamped while adjusted at anydesired: angle.

The frame clamping member 6 is clamped Q; to" the truck frame 1 by the bolts 8 which i pas sthrough-the plate 17. a This plate is provided with a series of holes 1Y corresponding to the holes 6" so that the bolts 8 maybe spaced at suitable distance" apart to receive various Referring to ig. 6 which isa vertical sectlon, and Fig.4 wh1ch 1s a transverse section,

it will be seen that the bolts 8 arefirstposi-v tioned in the apparatus by passing theinv through the partly hexagonal holes or. openings '6. and the'j'main portion of theframe clamp 6 securedto thevtru'ck frame by the bolts 8; Then the bolts 14: after slipping .on

the collars 15; are singlypassed through the large rectangular space 16 the lower one beingfirst, worked into its position and thejupper onefollowi'ng in" like manner. 7
